DM74AS161, Synchronous 4-Bit Counter with Asynchronous Clear DM74AS163, Synchronous 4-Bit Counter ©1984 Fairchild Semiconductor Corporation www.fairchildsemi.com DM74AS161, DM74AS163 Rev. 1.2 5 Absolute Maximum Ratings Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be A ripple counter is an asynchronous counter in which the all the flops except the first are clocked by the output of the preceding flop. Design module dff ( input d, input clk, input rstn, output reg q, output qn); always @ (posedge clk or The 74HC191 is an asynchronously presettable 4-bit binary up/down counter. It contains four master/slave flip-f lops with internal gating and stee ring logic to provide asynchronous preset and synchronous count-up and count-down operation. Asynchronous parallel load capability permits the counter to be preset to any desired value. DM74LS169A Synchronous 4-Bit Up/Down Binary Counter DM74LS169A Synchronous 4-Bit Up/Down Binary Counter General Description This synchronous presettable counter features an internal carry look-ahead for cascading in high-speed counting applications. Synchronous operation is provided by having all flip-flops clocked simultaneously, so that the ... verilog+code+for+4+bit+ripple+COUNTER datasheet, cross reference, circuit and application notes in pdf format.
